What to do if your boiler loses pressure - British Gas

If your boiler pressure reads less than 1 bar, it's possible that you might have lost water from the system, which needs to be replaced. This is where that filling loop (or filling link) comes in again! If the pressure gauge on your boiler indicates high pressure (above 2.75 bar), then you may need to bleed a radiator to bring the level down to around 1.5 bar. This can be tricky and, occasionally, dangerous; due to high
